WILLIAM WALKER CATO, OF HIGKSFORD, VIRGINIA.

IMPROVEMENT IN CU'LTIVATORS.

Specification forming part of Letters Patent No. 128,360, dated June 25,1872.

To all whom it may concern:

Be it known that I, W. W. CATO, of Hicksford, in the county ofGreenville and State of Virginia, have invented a new and usefulOombined Cotton and Corn Cultivator, Scraper, and Plow; and I do herebydeclare the following to be a full, clear, and exact description of thesame,reference being had to the accompanying drawing forming part ofthis specification, in which- Figure 1 is a side view, Fig. 2, a topview, the beam and handle being removed; Figs. 3, 4, 5, 6, 7, 8, and 9,plan views, representing the set of blades adapted to be used with theplow, shown in Figs. 1 and 2 Fig. 10, a perspective view of the castingB; Fig. 11, a rear elevation of the casting A and Fig. 12, a top view ofwing w.

' Similar letters of reference in the accompanying drawing indicate thesame parts.

The object of this invention is to provide for public use a light,simple, cheap, and serviceable instrument, which can be adaptedconveniently for use as acotton plow or scraper and a corn plow andcultivator; and the invention consists in the combination of the partsand the details of their construction, as hereinafter set forth.

In the drawing, A represents a casting, which operates as the point anddouble share of the 'pl0w,the same being made of triangular shape withits rear end rounded in, as shown at a a, and being concave on its underside and convex on its upper side. B is a casting, which constitutes theheel and standard of the plow, the same being provided with a convexrounded toe, b, at any angle required, which fits under the concaveplate A, and with a curved shoulder, c, which fits accuratelyagainst'the rear edge of the casting A in the recess a, the two castingsA B being securely bolted together at d, as shown in Figs. 1 and 2. Theplowbeam is supported on the standard in the usual manner, and isconnected to the rear projecting plate f by means of a brace, g, thehandle h being attached to the brace and the beam, as shown in Fig. 1.The standard is cast in a peculiar form, as shown clearly in Figs. 1, 2,and 10, its cross-section representing two sides of a triangle the apexof which is the front edge of the standard, which is formed sharp so asto cut readily through the dirt. On each wing of the standard, near itslower end, and just above the line of the casting A, is a square recessor socket, 0, having one or more bolt-holes. A series of cutters orwings, w 10 e0 10 shown, respectively, in Figs. 6, 7, 8, and 9, and ofthe form therein represented, is provided, each being constructed with asquared front end that fits accurately into the socket e, and with oneor more bolt-holes corresponding in number and position to the holesthrough the socket. The blades of these cutters are curved downward fromthe socket, and curved or twisted slightly so as to bring thecutting-edge in front and the cutting portion of the blade in aninclined position to make it work effectually. The bolt-hole in eachcutter is also enlarged at its front end in order to countersink thehead of the bolt and cause the parts to present a smooth surface. Two ormore other cutters, a u, are provided, each having the curved form androunded front end shown in Figs. 3 and 4, and each provided with aseries of notches, o o, cut in the front edge of the rounded end. Thesecutters are attached to the standards by means of a square plate, t,which accurately fits into the socket e. The plate is provided with aprojecting spur, c, at its edge, and with a bolt-hole, 0, at its center.Being fitted into the socket e the cutter a or u is placed upon it andone bolt serves to clamp them all to the standards; the square form ofthe plate 25 preventing its turning in the socket, and the spur c andnotches o preventing the cutter from turning, and also serving as ameans for adjusting the inclination of the cutter at any angle required.In connection withmy plow I also use a longer cutting, or, moreproperly, a lifting blade, m, one end of which is fastened to the top ofthe castingA, as shown in Figs. 1 and 2, while the other is supported,braced, and adjusted by means of an iron or wooden brace, n, attached tothe rear end of the beam. The lifter is cast or formed with a sort ofhub or lateral projection on its front end,which fits accurately into acorresponding socket in the part A so as to relieve the bolt of toogreat strain, and it is fastened in place by means of a bolt, r, Figs. 1and 2, which passes down through the center of the hub, and is providedwith a screw-nut on the under side of the plow.

This completes the construction of my improved agricultural instrument,and I will now proceed to describe its operation and advantages.

The first use of the plow after the ground is fallowed is, with the pairof cutters, moldboards, or wings w, Fig. 6, to lay off the rows forcorn, cotton, tobacco, or any other crop, or to open the furrows forsowing guano or manure of any kind. The next use is with the wing w,Fig. 3, on the right, and 20 Fig."

9, on the left, and with the scraper or lifter m above the little wingw. This adjustment is for plowing cotton the first time after it ischopped out. 7 The cotton will always fall down more or less, and thefunction of the scraper or lifter m is to run just under the ground andset up the young cotton, while the little mold-boards underneath willthrow dirt to it. The next plowing, for cotton, is with the wing w Fig.4, on the right side, and w, Fig. 9, on the left; not using the strip onat all after the operation of lifting the young cotton, above described.For corn, when young, I use the pair of wings 10 242 Their curvature isless than that of the other wings, and, when using them, the plow runsdeeper into the ground. When the corn is a little larger the pair ofwings w u; will be used, and the plow will not go quite so deep. Thelast plowing will be with the pair of wings w w when I wish to runshallow for corn, cotton, or any other crop.

The different wings will suit equally well for all the different kindsof crop at the proper stages of their cultivation. As a general thing noother plow, except this and the common turning-plow, will be needed forany ordinary agricultural operations; and, by properly using andadjusting the different wings, as occasion may require with differentcrops, they will so effectually destroy the grass that nearly all of theordinary hoe work can be dis pensed with.

Having thus described my invention, what I claim is- 1. The lifting-barm, constructed and adapted to be used in combination with the plow,substantially as described, for the purpose set forth.

2. The adjustable notched wings to u, in combination with the removableplates t and the plow-standard, having sockets 0 adapted to receive andhold the plates, when constructed in the manner and for the purposesherein set forth.
